Kayak Fish Finder Features:


There are many things that make a good fish finder. Everything from the size of the screen to the frequency the transducer works off will affect your day on the water.

Screen size

Since a kayak isn’t a huge fishing boat a large screen may actually be a hindrance. Fish finder screens range in size from 3 inches to upwards of 6. Being able to see the screen and the fish is easy on a screen 4 inches or larger. Some even use the high resolution screen of your smartphone or tablet to show you exactly where the fish are.


This is the part of the system that sends the waves to find the fish. Depending on the system a transducer can either be attached to the boat or dangle freely in the water. It is important to angle the cone, the part that reads the waves, in the direction you wish to fish. A wide angled cone will give you the best visual on the water below you and the fish it holds. These angles can range from 9 to 60 degrees. A rating of 20 degrees is a good starting point for people who like to fish in different water depths. Just keep in mind that the deeper the water the less sensitive the reading will be.


Each machine will work on different frequencies. Different frequencies allow you to fish in deeper or shallower water. For example, a shallow water fish finder will range in the 192 and 200 kHz frequency while deep water will use lower frequencies like 50 to 200.

Power source

Since you are using your kayak to fish you won’t have lots of storage space for a battery. There is a balance between performance and readability. A high resolution screen requires a high amount of power while a lower powered device will show readings slower and in less detail. Many fish finders have built in batteries that last upwards of 10 hours, while some run off large 12 volt car batteries.

Screen Resolution

The screen of your fish finder will be one of the most important parts. If you cannot see the fish clearly the whole system is useless. Resolution is measured in pixels much like that of a regular television. We recommend not getting a screen with a lower resolution than 240 x 160 as the detail won’t be high enough to distinguish clearly. A high resolution screen will start around 640 x 640 and increase from there. Just keep in mind a higher resolution screen will use more energy which can reduce its usability.

3D Sonar

Instead of a grainy set of dots on a screen 3D sonar shows a detailed view of the area under you. It will allow you to see the slope of the floor and even the plant life in great detail. This is an excellent feature as you will have the best idea of where the fish are and how many are populating the body of water you are in.


Make sure when purchasing your fish finder that it comes with a way to mount it to your rig. It can be cumbersome and make your day feel long if you have to keep one hand on your fish finder while you throw casts. Look for angled arms or stand that can easily connect to the edge of your rig. You will be able to wrap and necessary cords around the arm to make sure they don’t dangle in the water.


Depending on your use a GPS may be a nice gesture to have. If you travel to new lakes and fishing holes a GPS will allow you peace of mind of not getting lost. If you regularly stick to a few places you are familiar with a finder without a GPS can save you some money.
